ABOUT SIDEREAL ASTROLOGY

Sidereal astrology uses the literal placement of the planets in the constellations. Tropical astrology recons the vernal point (spring equinox) as 0 degrees of Aries. However, the vernal point has not been at 0 degrees of Aries for over 2,000 years, rendering the tropical zodiac inaccurate by 23 degrees.

Sumerian and Babylonian astrology yielded accurate descriptions and predictions for at least 4,000 years. However, Babylonian astrology was adopted by the Greeks, who created and applied both the element-modality system and erroneous planetary-rulership system to ancient astrology, resulting in inaccurate associations, which remain in use in modern astrology, and influenced Jyotish (Vedic astrology) heavily.

Free Workshop: More Than an Aspect — Dṛṣṭi in Indian Astrology 🔭

In Jyotiṣa, planets don't just sit in your chart — they look at each other.

Join Gary O'Toole for a free live workshop with the International Sidereal Astrology Association, exploring dṛṣṭi — the planetary "sight" that's often translated as "aspect," but works differently in important ways.

You'll learn: ✨ How aspects and dṛṣṭi differ — and why the distinction matters ✨ Why Mars, Jupiter, and Saturn are said to have "special sight" ✨ How to identify and interpret the most important dṛṣṭi in your own chart

🗓️ Saturday, October 24 ⏰ 4:00 PM BST / 11:00 AM EDT 💻 Live and free — everyone welcome. Replay available for ISAA members

Introducing a new course: Astral Sciences in Mesopotamia ✨

What did the sky mean to the people who first wrote it down?

We're so excited to share that Abbeygale Quinn is teaching Sumerian for Astrologers — the opening course in ISAA's new three-part program, Astral Sciences in Mesopotamia.

This isn't a survey of "ancient horoscopes." It's a deep dive into the Mesopotamian astral tradition on its own terms — its language, its religion, its history — so you can ask better questions of the evidence itself!

📜 ~3 months of live instruction
🗓️ Saturdays & Sundays, 11 AM–1 PM ET, starting January 9, 2027
🎥 Every class recorded — attend live or catch up later
💫 Taught by Abbeygale Quinn

Early registration is open through November 9, 2026 — and ISAA members save 25%.

October's lunar cycle seeds in the stars of Virgo — the largest constellation on the ecliptic. The Sun takes about 47-48 days to transit through these stars and had entered nearly a week after September 10th’s New Moon. October’s cycle is a continuation of this last with a few caveats. Virgo brings up themes around health & wellness, our daily routines, work life, and how we show up for others. Saturn and Vesta are also in opposition linking themes to discipline, slow and intentional efforts, and working within challenging obstacles. Attention could be directed toward finances, the career, and what it is really motivating how you pursue those things.

Ceres in Gemini adds tension from groups outside your close social circles. Ceres trines Gemini’s classical ruler Mercury, which is in hard aspect to Pluto (Capricorn), Jupiter (Leo), and Mars (Cancer) testing our ability to communicate and build rapport within a larger community circle. Mercury enters its Rx phase Oct. 24th just before the Full Moon, so the perceptive connections and rationalizations we’ve made previously may need to be revisited.

Venus Rx began Oct 3rd on the edge of Virgo and Libra bringing up themes around past obligations, relationship needs, what is fair and what is in need of balancing. The hard aspect to Mars in Cancer could influence sensitivity issues or acting from emotion & memory. Pluto’s influence to both Mars and Venus wants change, to confront the power imbalances and acknowledge tensions. This is an opportunity for expression, to negotiate terms of a relationship whether business, family, or personal connections. Tension could be good for partnerships as it's an opportunity to learn from past patterns and reconnect on a deeper level.

The south node is with Jupiter and fixed star Regulus hashing up old talents, pushing us toward accidental or inherited leadership roles, and in a way showing us how to rediscover our own personal power without the ego or arrogance getting in the way. The North Node in Aquarius brings themes around making choices based on our own humanitarian nature and as it moves into the stars of Capricorn we find our concerns become more about our greater humanitarian family and the systemic foundations supporting our collective network.

The Full Moon on October 25th lights up the Virgo/Aries axis which isn't typically talked about in non-constellational circles. Virgo’s detailed analysis and focus on improvement meets Aries' headstrong desire nature. Pluto in Capricorn's hard aspect intensifies pressure around independence and pursuit of exploring one's power as an individual within a collective framework.

The Plutonian extremes of this cycle could manifest as unexpected change or unintentional destruction leading to creation. Venus w/ Sun shows again the emphasis on our relationships and perhaps where we’ve lacked to embrace personal empowerment in the past. Jupiter’s trine Moon in its highest expression encourages transparency and honoring personal truths. Yes there is much opportunity for making shifts for realignment this month. Take it slow and exercise patience as Plutonian influences can be unpredictable and bring the smoke!
